twoPhaseEulerFoam

Hi,everyone. I just met some troubles by using the solver named twoPhaseEulerFoam.
I tried to run the case 'bubbleColumn' which turbulent model is LES, and it can run normally without changing anything.
However,the case can't run normally when the value of 'convertToMeters' changed from 1 to 0.01 in the blockMeshDict file.blockMeshDict.c

Your solver runs into negative volume fraction of air and then your temperatures drop below absolute zero and the simulation crashes. This happens when your solution doesn't converge. Check this thread for answer: http://www.cfd-online.com/Forums/ope...ultiphase.html .
